τ-Guard: Recalibration-Invariant, Label-Free Drift Detection for Visual Recognition Systems via Cross-Signal Rank-Agreement Decay

The paper introduces (τ)(\tau)-Guard, a label-free drift detection method for visual recognition systems that achieves provable invariance to model recalibration by monitoring the rank agreement between predictive entropy and feature-space novelty scores, thereby avoiding the false positives that plague existing confidence-based monitors while maintaining sensitivity to genuine distribution shifts.

Too Symmetric to See: Diagnosing Over-Invariance in Finite-Symmetry Geometric Learning

This paper identifies and quantifies "over-invariance" failures in geometric learning where excessive symmetry discards critical phase information, proposing Projective Character Pooling (PCP) as a targeted repair mechanism that effectively restores phase channels and improves diagnostic flatness compared to standard magnitude-only models, though it remains a scoped solution rather than a universal replacement for orbit averaging.
